“…Distillate output has been increased up to 3.61 kg/day through addition of char coal. Design modification may also be performed through geometry variation as estimated by Gad et al [23]. Water productivity of a conical solar still has been compared to that of conventional solar still and measured to be 3.38 and 1.93 dm 3 /m 2 /day, respectively.…”

Despite the importance of the desalination process in removal of water salinity to produce fresh drinking water, it is an energy-consuming process. Therefore, the use of solar energy as an alternative and free energy source has an important role in enhancing the efficiency of the desalination process. This paper presents an experimental investigation using solar chimney to enhance the desalination process, where a modification to the conventional solar stills has been made. A mathematical model describing air flow inside the solar chimney has been constructed using Computational Fluid Dynamics (CFD). The commercial CFD package fluent release 6.3 has been used in this paper to express the air flow and temperature distribution inside solar chimney. Furthermore, the process parameters such as seasonal temperature, salt concentration, water depth and type of solar desalination unit have been examined to find the best operating conditions. The desalination process has been recommended to be carried out under permissible operating conditions in sunny days, with water depths ranging from (1-2 cm) and low salt concentration ranging from (3.5-8%). The modeled data has been verified with experimental data and the verification results have been estimated at 14%. Simulation results showed that water desalination has been improved by 30%.

“…A variety of sensible heat storage materials [10][11][12] and latent heat storage materials [13,14] used to increase the yield after sunset. Different still designs were used like Pyramid [15], conical [16] triangular pyramid [6] and hemispherical stills [17] to improve the yield. Operational parameters like depth of water in the basin has significant impact on the yield and it reduces with increase in the water depth [18].…”

Effect of the orientation on the yield of the stills has been discussed in this experimental work. Two identical modified stills S1 and S2 fabricated, each with 0.5 m 2 of basin area. Stills had transparent glass walls with trough to collect the condensate from the walls. Mixture of highly porous coco peat and charcoal were used as basin material. Still S1 had North-South (N-S) orientation with cover slope due south whereas still S2 had East-West (E-W) orientation with cover slope due east. Experiments were conducted by changing the water quantity in the solar stills ranging from 5 to 10 kg. Maximum distillate output of 5.67 L/m 2-d was obtained for S1, whereas it was 5.45 L/m 2-d for S2 for an average solar radiation intensity of 695 W/m 2 (25 MJ/m 2-d). The increase in the yield of S1 over S2 due to the orientation was found to be in the range of 0% to 11%.Use of transparent walls increased the condenser area by 78.4%.The distillate water cost per litre was estimated as Rs. 0.86 (0.013 US$) and Rs.0.90 (0.014 US$) for S1 and S2 respectively. Energy payback time (EPT) for stills S1 and S2 was estimated as 4 months.
